Abstract

In un cuscinetto a rotolamento per il supporto di alberi spostabili in modo limitato assialmente (15) o simili, consistente in elementi cuscinetto (1, 2) con piste cilindriche o piane (5, 6) e con corpi di rotolamento (4) sistemati nel mezzo in una gabbia (3) una pista (6) viene delimitata da bordi (7) con superfici d'appoggio (8) di preferenza obliqua.Per evitare danneggiamenti dei corpi di rotolamento (4) nella posizione assiale finale di un elemento cuscinetto (1) rispetto all'altro elemento (2), la gabbia (3) possiede almeno da un lato frontale dei segmenti elastici (9), che ingranano in settori ad estensione radiale (10) in una scanalatura (11) dell'uno (2) o dell'altro elemento cuscinetto (1), dove nella posizione assiale finale di un elemento (2) rispetto all'altro (1), i settori ad estensione radiale (10) della gabbia (3) sono sistemati appoggianti sulle superfici laterali (13) della scanalatura (11).(figura 1).In a rolling bearing for the support of axially limited movable shafts (15) or the like, consisting of bearing elements (1, 2) with cylindrical or flat raceways (5, 6) and with rolling bodies (4) arranged in the means in a cage (3) a track (6) is delimited by edges (7) with support surfaces (8) preferably oblique. To avoid damaging the rolling bodies (4) in the final axial position of a bearing element ( 1) with respect to the other element (2), the cage (3) has at least one front side of the elastic segments (9), which engage in sectors with radial extension (10) in a groove (11) of the one (2 ) or of the other bearing element (1), where in the final axial position of one element (2) with respect to the other (1), the sectors with radial extension (10) of the cage (3) are placed resting on the lateral surfaces ( 13) of the groove (11). (Figure 1).
